For the sentinel lymph node mapping procedure, a blue dye, a radioactive colloid, and/or an indocyanine green (IC-Green) dye will be injected into your cervix during your surgery. The study staff will then use a device that detects radioactivity and that looks for lymph nodes stained with the dye(s). When the study staff locates the sentinel lymph nodes, they will remove them. The sentinel lymph nodes will then be sent to a lab where a pathologist will check them to see if they contain cancer cells. Other lymph nodes may be removed as part of your standard of care surgery if your surgeon thinks it is in your best interest.
